Abstract
Description
- The present invention relates to a conveyor device for parts, particularly applicable to the conveyance of lightweight machined parts through washing machines, in which said parts are successively subjected to operations of immersion in washing liquid vats and/or solid material blasting and hot air jet drying.
- Machines for washing machined parts are well known. Said parts are conveyed through the interior of such machines by various systems, the most used among which are those formed by two pairs of step by step feed bars.
- All these systems provide for the intermittent feed of the parts and the halting thereof in front of washing liquid jet stations, and hot air jet drying stations.
- When dealing with relatively lightweight parts, unless there is an adequate retaining system for them in front of each washing and/or drying station, the action of the jets may even dislodge the part, which may become misplaced in the feed system and make the washing inoperative, since the jets do not coincide with the locations of the part to be washed.
- The conveyor device of the present invention allows all the aforesaid drawbacks to be overcome and thereby achieve safe, reliable conveyance of lightweight parts along the interior of washing machines, without undesirable movements thereof, causing deficient washing.
- Essentially, the device in question is characterised in that it comprises a conveyor belt for said parts, provided with a continuous feed movement, on both sides of which there are disposed respective endless chains of a conventional articulated link type, which rotate synchronously around respective pairs of sprockets associated with a gear and transmission bar unit, driven by a motor means providing them with an intermittent movement, there being opposedly disposed at least one first pair of front retaining stop members, fixedly attached to respective links of said chains and adapted to hold a part by the front upper leading portion thereof, when said part abuts said pair of retaining stop members, just after the links to which said front retaining stop members are attached have passed beyond the first pair of sprockets, and at least one second pair of rear retaining stop members, adapted in turn to retain said part by the trailing end and upper trailing edge thereof, when the links to which the rear retaining stop members are attached have just passed beyond the first pair of sprockets, such that the part is held by both pairs of retaining stop members on the conveyor belt, throughout the whole of its passage through the interior of the washing machine, after which the part remains deposited on the conveyor belt, but released from the grip of the retaining stop members, from the time when the links to which said retaining stop members are attached start to move successively in front of said second pair of sprockets.
- According to a further feature of the invention, above the conveyor belt and below the trajectory of the lower surface of the retaining stop members, there are disposed two lateral longitudinal guide members, adapted to prevent undesired lateral movements of the parts before they are retained by the retaining stop members.
- According to a further feature of the invention, each of the chain sprockets is associated with a gearbox, the gearboxes being coupled together by corresponding shafts and transmission bars, for intermittent synchronised movement thereof.
-
- Figure 1 is a schematic plan view of the forward portion of the chains and of the conveyor belt;
- Figure 2 is a front elevation view of the overall device of the invention; and
- Figure 3 is a perspective view of the ensemble of Figure 2.
- In the drawings it may be seen that the conveyor device of the invention, applicable to the conveyance of
lightweight parts 1 through parts washing machines, comprises aconveyor belt 2 on both sides of which at a slightly higher level there are disposed respectiveendless chains 3, of conventional type having mutually articulatedlinks 4. Saidchains 3 rotate around respective pairs ofsprockets 5, associated to a gear and transmission bar unit driven bydrive means 6, providing them with an intermittent movement. - On the
chains 3 there are disposed opposedly a plurality of pairs of front retainingstop members 7, fixedly attached tocertain links 4 of saidchains 3, with each of said pairs being adapted to retain apart 1 by the front upper leading portion thereof when saidpart 1 abuts said pair ofstop members 7, after thelinks 4 to which thestop members 7 are attached have just moved beyond the first pair ofsprockets 5. - In the same way, a like number of pairs of rear retaining
stop members 8 are provided, with each being adapted to retain in turn apart 1 by the rear portion and upper trailing edge thereof, when thelinks 4 to which the retainingstop members 8 are attached have just passed beyond the first pair ofsprockets 5. - Each
part 1 is thus retained by a pair of front retainingstop members 7 and by a further pair of rear retainingstop members 8 on theconveyor belt 2, throughout the whole of its passage through the washing machine. - At the end of such passage the
part 1 remains on theconveyor belt 2, but released from retention by the retainingstop members links 4 to which said stops 7 and 8 start to pass successively by the second pair ofsprockets 5. - Above the
conveyor belt 2 and below the path of the lower surface of theretaining stop members 7 and 8 (Figure 2) there are disposed two longitudinallateral guides 9, adapted to prevent undesired lateral movements of theparts 1, before these are retained by the frontretaining stop members 7. - Each of the
sprockets 5 of thechains 3 is associated with agearbox 10, the fourgearboxes 10 being coupled together bycorresponding shafts 11 andtransmission bars 12, to obtain synchronised intermittent movement thereof. - Having sufficiently described the nature of the invention, as well as the way of reducing it to practice, it is declared that everything which does not alter, change or modify the fundamental principle thereof, may be subject to variations of detail.
